Dog tricks wallpaper.Whoever said you can?t teach an old dog new tricks, must not have owned a dog. If dogs are anything, they are extremely intelligent and can learn many new things given the chance to show you. When training your dog, keep in mind that yelling, hitting, cursing or punishment is uncalled for, as dogs will retreat backwards the more they are yelled at. Many people like their dogs to wear clothing items, hats, sunglasses, bandanas or even complete theme items or costumes. Dogs, by nature, are not always happy about this decision. Start desensitizing or training your dog to tolerate these items by having the dog sit and gradually moving the item toward the dog. Praise the dog as the item gradually gets closer before the dog starts to move away. As the dog becomes comfortable with the item it can be brought against the body.
